ROLLER-BEARING.

Specification of Letters Patent.

Patented March 3, 1908.

Application filed October 26, 1907. Serial No. 399,246.

To all whom t may concern.'

Be it known that I, FRANCIS G. SUsEMIHL, a citizen of the United Statesof America, residing at Detroit, in the county of l/Vayne and State ofMichigan, have invented certain new and useful Improvements in Roller-Bearings, of which the following is a specification, reference being hadtherein to the accompanying drawings.

In roller bearings of ordinary construction, the friction rolls eithercontact with each other so that there are two surfaces traveling inopposite directions, or else are confined by spacing members or cages inwhich they are journaled, thereby introducing cylindrical bearings inthe system. Furthermore these spacing rolls are usually grouped aroundor are external to the main shaft or axle, thereby increasing the sizeof the bearing as a whole and making it cumbersome. Because of thisdisposition of the rolls they must necessarily be kept as small aspossible,-

which increases the friction and diminishes the readiness with whichthey revolve, and also makes them liable to crush when under heavy load.

This invention relates to a roller bearing wherein the spacing rolls arehoused within themain shaft or axle and wherein the engagement betweenall the peripheral surfaces of the assembled bearing is a rollingcontact with no slipping or retarding of any one surface in relation toits opposing surface, and wherein the members are of such size as torender the bearing capable of sustaining extremely heavy loads andmoving freely thereunder.

The invention consists in the matters hereinafter set forth, and moreparticularly pointed out in the appended claims.

Referring to the drawings, Figure 1 is a view in section of a wheel andassembled bearing embodying features of the invention.

Fig. 2 is a view in section on line -:E of Fig.

1. Fig. 3 is an enlarged view of the end of the bearing, with one partof the main shaft removed. Fig. 4 is an enlarged view taken inlongitudinal section through the main shaft and wheel, showing a centerspindle and bearing rollers in elevation and a modified form of hub.

As shown in the drawings, a wheel 1 having a body adapting it for anyparticular purpose desired, is provided with a hub whose bore has acentrally disposed peripheral trated in Fig. 4. A pair of axially alinedstub shafts 6 which constitute the -main shaft or axle of the bearing,are secured in axial alinement in the sides 7 of a suitable frame as bybolts 8 engaging flanges 9 on the outer ends of the stubs, with a spacebetween their adjacent ends corresponding substantially to the width ofthe channel 2 or the distance between the collars 3.

The ends of the stub shafts are recessed or counterbored and a centralspindle 10 which is journaled on end bearings 11 in axial sockets in theshafts, has a iange 12 near each end lying concentrically within theadjacent recess.

The wheel is rotatably mounted on a plurality of bearing rollers 13whose reduced ends 14 act as journals interposed between the collars andthe shafts in simultaneous contact therewith, and whose bodies are heldin parallel spaced relation by a set of spacing rolls 15 whose centralportions each contact simultaneously with a pair of the bearing rollers18, and whose end journals 16 are interposed between the peripheries ofthe spindle iianges 12 and of the shaft recesses in simultaneous contacttherewith. The shoulders between the bodies and journals of therespective rollers and on the outer sides of the iianges are preferablyslightly beveled back or rounded to minimize any end thrust friction.

The ratios between the diameters of the contacting peripheries of theseveral elements of the assembled bearing are such that there is noslipping and that the bearing rollers are maintained in proper spacedrelation without engagement with or confinement in a stationary cage.Furthermore all contacting peripheries travel on each other in the samedirection so that there is cient size to carry any desired load withoutmaking the assembled bearing cumbersome. Furthermore the arrangementminimizes the number of rollers necessary, the arrangement of four asillustrated being quite sufficient for ordinary purposes, although`obviously they may be increased if desired. Again as each set of rollersrevolves around the axle axis in the same direction, the bearing isstarted from rest very readily even under very heavy loads and there isno wedging or camming action between the parts.

Obviously the details of the hub construction and of the frame and ofthe method of securing the stub axles therein may be varied to suitdifferent purposes, and l do not care to limit myself to any particularform or arrangement of parts.

A roller bearing comprising a mainaxle consisting of a pair of axially alined fixed stub shafts havingcylindrically re-' cessed and separated adjacent ends, a spindlejournaled between the shafts in axial alinement therewith, a set ofspacing rolls revoluble around the s indle within the shafts, a set ofbearing ro lers revoluble around the shafts maintained in separatedparallel relation by the spacing rolls, and a hub rotatable on thebearing rollers.
